Stokke ・Tripp Trapp high chair tray ・EZPZ Happy Mat I think they can still be used! I wiped them down with alcohol, but both have signs of use as follows: Tray 　There is yellowing if you look closely. Happy Mat 　There are water droplet marks on the back, and yellowing if you look closely at the indentations. The shipping method is to put everything in the tray box, wrap it in bubble wrap, and ship it. (Since everything is stored in the tray box, the box is slightly deformed. *Picture 8) Please purchase only if you understand the above. If you have any questions, please comment.
